Racemic Calcium Pantothenate is a mixture of the calcium salts of the dextrorotatory and levorotatory isomers of pantothenic acid. It contains NLT 5.7% and NMT 6.0% of nitrogen (N), and NLT 8.2% and NMT 8.6% of calcium (Ca), both calculated on the dried basis.

[NoteThe physiological activity of Racemic Calcium Pantothenate is approximately one-half that of Calcium Pantothenate. ]

Analysis: Dissolve the Sample in 15 mL of carbon dioxide-free water in a small flask. As soon as the solution is complete, add 1.6 mL of 0.10 N hydrochloric acid, and then add 0.05 mL of phenolphthalein TS.
